Origin: An import rather than a native French figure: it renders the English to cost an arm and a leg, and Canadian French sometimes extends it with et la moitié de l'autre. The English original is itself unsettled, spreading in the early 20th century. Proposals include the older to give one's right arm for something, military stripes worn on the sleeve and stripped away with a demotion, and portrait painters charging extra to include limbs — that last one widely repeated and poorly supported.
